SCORING ATTACHMENT .FOB. VENEER-LATHES.

Specification of Letters Patent.

Patented May'21, 1912.

, To all whom it may concern:

Be it known that I, JOHN VAN MILL, J r., a citizen of the United States,residing at Gladstone, in the county of Delta and State of Michigan,have invented new and useful Improvements in Scoring Attachments forVeneer-Lathes, of which the following is a specification.

The general object of the invention is to facilitate the operation ofsecuring in their adjusted positions on a veneer lathe the scoring tooland the stock or carrier therefor.

Other objects will appear and be better understood from the followingdescription taken in connection with the accompanying drawings, inwhich,

Figure 1 is a vertical section of the device applied in operativeposition on a veneer cutting lathe. Fig. 2 is a detail perspective ofthe scoring tool with a portion of the head thereof broken away. Fig. 3is a perspective of the operating lever. Fig. 4 is a cross section onthe line 4l4; of Fig. 1.

5 designates a portion of the bed plate of an ordinary veneer cuttinglathe. 6 the usual scoring knife, and 7 a fragment of a log which isbeing scored by theknife 6. A dove-tail recess 8 in the bed plate 5receives the beveled heads 9 of clamp bolts 10 which extend through thestock 11 and are held by nuts 12. The scoring knife 6 slides in a recess14 opening through the bottom and opposite ends of the stock 11 and isactuated to do so by an operating lever 15having a tooth 16 which isreceived by a notch 17 formed in a head. 18 which latter has an offsetportion 19 provided with a recess 20 to receive the knife or scoringtool 6 and an ad justing screw 21 screwed into an opening in one side ofthe head is adapted to bind on the scoring tool so as to adjustablysecure the head 18 thereto. The toothed end of the lever 15 is roundedand arranged in a vertical recess 22 formed in one end of the stock andcommunicating with the recess 14, and has an eccentric hole to receive apivot pin 24 passing transversely through the stock 11. When the leveris depressed as shown in Fig. 1 the sharpened end 25 of the scoringknife 6 is projected beyond one end of the stock and into engagementwith the work. When the operating lever is moved upwardly from the stockthe tooth thereof retracts the scoring tool. By adjustably securing thehead at points nearer the rear end of the tool than that shown in Fig. 1the said tool will penetrate the work for a greater distance. A camextension 26 on the pivoted end portion of the lever and to one side ofthe tooth 16 presses downwardly on the scoring tool while the lever isbeing depressed to the position in Fig. 1. This has the effect of movingthe stock away from the bed plate 5 and thus causing the beveled heads 9of the bolts to wedge in the dove-tail recess 8 and lock the stockagainst sliding movement on the bed plate, this locking of the stocktakes place at the time the tool or knife is fully projected.

In use any number of the devices may be connected to the bed plate ofthe lathe and when the levers thereof are moved outwardly, may beadjusted on the bed plate by sliding the stocks through the dove-tailrecess of said bed plate. After the stocks are positioned opposite tothe portions which are desired to be scored on the log and after h thescoring tools are adjusted so as to enter the log to a predetermineddepth, the levers are depressed whereupon the parts will be locked intheir adjusted positions as previously described.

Although I have shown and described one embodiment of my invention it isto be understood that I am not to be limited to the specific structureherein shown and claimed nor to the particular arrangement of the partssince it will be seen that various changes may be made, in the scope ofthe appended claims without departing from the spirit or sacrificing anyof the advantages of the invention.

What I claimias new is:

1. In a scoring device for veneer lathes, in combination with a bedplate, a stock adjustable thereon, and a scoringtool adjustable on thestock; of a lever pivoted to the stock and adapted to adjust the scoringtool,

and simultaneously lock the stock and scoring tool in their adjustedpositions.

2. In a scoring device for veneer lathes, in

combination with a stock, and a movable scoring tool carried thereby; ofmeans for moving the scoring tool and including a head adjustablysecured to the tool, and an operating lever adapted to engage the headoperating lever pivoted to the stock and having a tooth interlocked withthe head.

4. In a scoring device for veneer lathes, in combination with a stock,and a movable scoring tool carried thereby; of means for moving thescoring tool and including a head adjustably secured to the tool and anoperating lever pivoted to the stock and having a tooth interlocked withthe head and further having a cam adapted to bind on 10 the tool whenthe lever is in one position, for the purpose described.

In testimony whereof I afliX my signature in presence of two witnesses.
